z claims. (cl. zzz-2.6211` The present invention relates to improvementsin dispensing devices, and its principal object is to provide a devicefor dispensing liquid from Aa `large container. in limited, measuredamountsQL. r d My invention is principally intended for the dispensingof liquid colee or'softr drinks' from containers which may hold a numberof gallons, in smaller quantities, suicient to fill a drinking cup orglass, the quantity being measured for each dispensing operation.

More particularly it is contemplated to provide a dispensing device inthe form. of a valve, in which the movable valve member itself serves asa measuring device and is designed to receive a desired amount of liquidwhen in one position and to discharge the said amount when in anotherposition.

It isfurther proposed to provide a dispensing device which is simple inconstruction, effective in operation, sanitary, which may be suspendedfrom the bottom of the main container or mounted within the latter, isoperated `by a slight turn of a handle' through a limited angle, and

readily lendsvitself to coin cont-rol, if desired.

Further objects and advantages of my invention will appear as ,thespecification continues, and the new and useful yfeatures of mydispensing device will be fully defined in the claims hereto attached.

The preferred form of the invention is illustrated in the accompanyingdrawing forming part of this application, in which:

Figure l shows a side view of my dispensing device, as suspended from aliquid container;

Figure 3, an end View, as seen from the right-hand side;

While I have shown only the preferred form of my invention, I wish tohave it understood that various changes or modifications may be madewithin the scope of the claims hereto attached, without departing fromthe spirit of the invention.

Referring to the drawing in detail, my invention com prises in itsprincipal parts, a cylindrical housing 10 having a frusto-conical bore,as at 11, a frusto-conical, hollow valve member 12 iitting in the boreand revolvable therein, means shown at 13 for interlocking the cylinderand the valve member, a handle 14 for operating the valve member, meansfor limiting the rotary movement of the latter member and suitableportions positioned to allow of valve filling and dispensing operationsand of venting during said operations.

The housing 10 is in the form of an elongated cylinder open at both endsand formed with a conical or tapered inner face which extends from endto end. It is susj L2,775,375 d Patented vDec.`l2l5,` 1.956

2 pended, in the formshown, from the containeror tank A, substantiallymidway its length, by` a conduit 15 which connects with the intakeconduit 16 of the housing.

. The cylinder thus occupies a horizontal position underneath the tank,but also may be mountedwithin the tank,

opening directly into the tank.

The valve member `12 has an outer taper tting the taper of uthe* housingand, is of substantially the same length as theghousing, so as to extendthrough the same from end to end and to form a liquid-tight beatingtherewith. Both ends of thevalve member are closed, as at 17 and 18, andthe valve member is hollow throughout, with the `inner wall facesrunning paralleltothe outer wall `faces, the valve memberbeing designedand proportioned to hold a immediately above the floor thereof, with the`intake port v limited, measured `amount of liquid, having-the capacityof a drinking cup or glass.l

. When the valve member is fully inserted, to form a liquid-tight seal,its inner `end 17 registers with the corresponding lend of the housing,`as shown, and a sealing ring 19 is made to overlie the joint between thefaces. The valve member is `held in this position under tension by meansof a threaded stud 20 projecting axially from the valve member, aU-shaped washer `21 straddling the stud and bearing on the sealing ring,a coiled spring 22 surrounding the stud, and a nut 23 threaded on theend of the stud and causing the spring to exert adjustable pressure onthe slotted washer and the sealing ring.

The outer end 18 of the valve member has a stem 24 projecting axiallytherefrom, the stem carrying the handle 14 by means of which the valvemember may be rotated. Rotary movement of the valve is limited to arelatively small angle by means of an `arm 25 projecting from `the stemand engaging with either one of two stop members 26-27 projecting fromthe housing. y Y r The housing has an outlet port 28 in the bottomthereof, near the outer end 18, that is, at the large end of the conicalvalve member, so that all the liquid may escape from the latter when thevalve `is in discharge position. `An outlet conduit 29 connects with theport 28.

The valve memberhas an intake port 30 which registers with the intakeport 16 of the housing when the handle 14 is in the full line positionof Figure 3. The valve member also has an outlet port 31 in thetransverse -plane of the outlet port 28 and adapted to registertherewith when the handle 14 is swung into the dotted line positionshown in Figure 3, which movement throws the intake port 30 out ofregistry with the port 16. The handle cannot be thrown beyond either ofthe end positions on account of the stops 26--27.

The housing has a vent opening 31 connected to a vent conduit 32 whichleads to an elevation labove the liquid level in the tank, and the valvemember has two corresponding vent openings 33 and 34, which are made toregister with the vent opening in the housing, one in the illingposition of the valve member and the other in its discharge position. y

In operation, with the tank filled with liquid to be dispensed and thevalve member in the `position shown, the valve member will be lled toits capacity, the outlet being closed. When the handle 14 is turned tothe dottedline position, the intake valve will be closed and the outletwill be opened for discharge of ythe measured amount of liquid throughthe outlet tube 29 into a cup or glass held underneath its dischargeend.

The valve member is held in operative position by the spring 22, whichat the same time presses the sealing ring 419 upon the joint between the`housing and the valve .zontally supporting the housing, with vone ofthe ports presented upwardly to -form -an intake and the other portpresented downwardly to forman outlet, means for'adkinitting aliqud tothe intake port, 'and a hollow'valve member adapt-ed for'holding ameasured `quantity 'of s liquid and having Aa lconical wall dimensionalito have 'a revolving t in the housing and having int-alte and outlet'ports adapted 'for select-ive registering with the corresponding ports-in the housing, means 'for rotating said valve bet-Ween receiving anddispensing positions for alternate filling and dispensing operations,one 4end of the valve member being 'ush with the corresponding end ofthe housing so as to form an annular joint therewith, a sealing ringcovering 'said joint, and spring means urging the sealingring uponthe-end of the housing and the end of the valve upon the sealing ring,said spring means comprising a threaded stud projecting axially fromsaid end of the valve, a U-shaped washer straddling the stud and bearingon the sealing ring, a coiled spring surrounding the stud and bearing onthe washer, and a nut `threaded on the-'stud nand bearing 'on thespring;

2. The structure delined;` in claim 1 wherein a vent is provided in saidhousing and said valve member is provided With a pair of vent openingsin a common transverse plane, one of said vent openings registering withsaid vent when the valve member is in filling position, and the other ofsaid vent` openings registering with said vent when the valve member isin dispensing position and being opposite the exhaust port in aA planeextending substantially diametrically through the exhaust port.
